Roots: All things being equal, by Emma Bell in chalkdust magazine

“The equals sign was invented as shorthand by Robert Recorde, a Tudor mathematician and doctor who published widely on a variety of topics. He was born in Tenby, Wales in around 1510, and died in Southwark in 1558 whilst in prison for not paying a fine.”

"The mathematician's patterns, like the painter's or the poet's, must be beautiful; the ideas, like the colours or the words, must fit together in a harmonious way. " G H Hardy, A Mathematician's Apology (London 1941).
